This paper describes the W-band fully polarimetric radiometer design and the measurement results of material's emissivity of rubber sheet and water as examples using developed radiometer. The measured brightness temperatures of sample materials depend on incident angle. For this angle dependent measurement, the test set-up was designed. Using the measured brightness temperature, the characteristics...
In this paper, we have investigated the characteristics of road surfaces status depending on electromagnetic polarization in vertical and horizontal, respectively. The emissivity of road surface of V-, H-polarization shows the different brightness signal level in receiver and it can detect by the experiment the different road surface status like dry, wet or ice covered road. This technology can be...
In this paper, we developed and experimented of the W-band 1-D focal plane array (FPA) passive imaging radiometer which was called by Millimeter-wave Imaging Radiometer Equipment (MIRAE). This consists of quasi-optics including a dielectric aspheric lens and a metal mirror as a reflector, 30 channels FPA receiver based on the direct conversion type, scanner, image processor and displayer. To get 2-D...
